Ryan Porteous should be the subject of a transfer battle between Celtic and Rangers, according to Kris Boyd.

The big defender was immense on his Scotland debut last week, strolling through the 0-0 draw with Ukraine.

Now 23, the Hibs man is available on a free transfer in the summer after the Easter Road side failed to secure a new long-term deal.

And Boyd reckons transfer offers should be a no-brainer for Scotland's big two.

He told The Scottish Sun: "If Rangers and Celtic are not already fighting it out for the signature of Ryan Porteous then they should be.

"The Hibs defender is out of contract in the summer and he’ll be the perfect fit for either of the Old Firm, who need central defensive reinforcements.

"People might be surprised by me touting him for a big move as I have been critical of him in the past.

"Yes, some of his antics infuriate you but I have never ever questioned his ability.

"Porteous’ performance on his Scotland debut against Ukraine shows when he’s on it then he’s as good as any central defender in the country.

"It has been mentioned that his display under the utmost pressure in Poland was a one-off. It wasn’t.

"There have been plenty of other top-class performances in a Hibs jersey over the past couple of seasons.

"Unfortunately they get lost or forgotten amidst all the other baggage that comes with the 23-year-old.

"Too often a lack of discipline on and off the park overshadows the good stuff.

"His reputation does go before him at times which is a shame because he certainly has bags of talent."
